97 Gettext translation declarator

• default.mo: module global, loaded on every request of current module
• admin.mo: Admin area (admin and block)
• block.mo: Module block

Use poedit to extract module language items:

• _a(), t() => admin.mo
• _b() => block.mo
• __(), _e() and others => default.mo

Block Templates

• just block templates ( phtml ) files should have _b ,

Front & Admin templates

• Front and admin templates should have _e
• but it's clearer to use for Admin _a

Admin & Block config

• All codes on config files should have _a or _t
• Even for block : must use _a
